LONDON - British authorities say the fossilized skull of a giant sea monster has been found off England's southern coast. The fossil came from a pliosaur, a ferocious predator that lived in the oceans 150 million years ago. The skull was discovered in Dorset by a collector and measures 2.4 meters (8 feet) in length. The discovery was announced Tuesday. Scientists believe the creature would have been about 16 meters (52 feet) long.

A rare dinosaur skull unveiled by University of Calgary paleontologists Thursday was literally hiding in plain sight.

Even with Prof. Darla Zelenitsky pointing out the eye socket of the massive pachyrhinosaur's skull, it still looked like just a giant chunk of rock.

And, with it being found inside the town limits of Drumheller — billed as the dinosaur capital of the world — it probably had hundreds of prehistoric enthusiasts traipsing over it for decades before anyone notice.

An unassuming lump found on a Sussex beach in 2004 contains the first known fossilized brain tissue from a dinosaur.

The 133-million-year-old fossil belongs to a relative of Iguanodon, an iconic herbivorous dinosaur that lived during the early Cretaceous. The fossil mostly consists of an endocast—a sediment cast of the skull cavity where the dinosaur’s brain resided.
